Metal fine particle dispersant comprising a hyperbranched polymer having an amino functional group or imino functional group at the terminal

摘要

PPROBLEM TO BE SOLVED: To provide a dispersant for metal fine particles excellent in ability to disperse metal fine particles, and a thin film or a cured film with high concentration of metal fine particles by using the dispersant. PSOLUTION: The dispersant for metal fine particles comprising a highly branched polymer having am amino functional group or an imino functional group at the terminal and a weight-average molecular weight measured by polystyrene conversion using gel permeation chromatography of 1,000 or 2,000,000; a composition including the dispersant for metal fine particles and metal fine particles; and a thin film or a cured film obtained from the composition are provided.
